Re: [AFMUG] PMP450 vs. ePMP

[Jesse DuPont]

Maybe ePMP has a lower threshold for bit errors and simply won't let them stay connected to the AP? Just guessing, I have no idea.

It doesn't make any sense that two different radios running on the same frequency putting the same amount of power into the same antennas would give significantly different signal levels... The closest thing I've done to a comparison was playing with a Force 200 2.4ghz in wifi mode... there didn't seem to be a significant difference between it and a PowerBeam connecting to the same AP.

With low SNR, I think it’s kind of like             arguing Ferrari vs Porsche for off road racing, neither             will be able to show off its capabilities.
